Detailed Description

Table class.

Library: dataccess

The IliRowPtr class defines objects that hold the index of a row in a given IliTable object. These objects take care of adjusting the row index whenever the row moves in its table (or when other rows are inserted or deleted before it). An IliRowPtr is obtained by calling the IliTable::getRowPtr member function.
